cosine (n)
ratio of the adjacent side to the hypotenuse of a right-angled triangle
cosine Sentence Examples
- In trigonometry, the cosine of an angle is defined as the ratio of the length of the adjacent side to the length of the hypotenuse in a right triangle.
- The cosine function is often abbreviated as cos in mathematical notation.
- The cosine of 0 degrees is equal to 1, as the adjacent side and hypotenuse coincide in that case.
- Mathematicians use the cosine function extensively in fields such as physics, engineering, and computer science.
- The graph of the cosine function oscillates between -1 and 1 as the angle varies from 0 to 360 degrees.
- Calculating the cosine of an angle involves dividing the length of the adjacent side by the length of the hypotenuse.
- Trigonometric identities involving cosine, such as the Pythagorean identity, are fundamental in mathematical analysis.
- The cosine of complementary angles is equal, as they share the same adjacent side and hypotenuse.
- The cosine rule allows for the calculation of the length of a side in a triangle when the lengths of the other two sides and the included angle are known.
- In applications such as signal processing, the cosine function is used to model periodic phenomena and analyze waveforms.
